Surgical protocol and outcome for sigmoidovesical fistula secondary to diverticular disease of the left colon: A retrospective cohort study

Adequately performed CT followed by colonoscopy is the mainstay for diagnosis. Type 1 SVF should be treated in a single stage by complete resection and immediate anastomosis without a stoma. Type 2 cases are best managed in two stages while those with type 3 SVF are emergently managed by three stage procedure. Treatment of type 4 should be individualized.
